Latest / The Productivity Podcast with Fexingo: Output, Efficiency, and Long-Term Economic Growth / How The Elevator Changed Office Productivity
Transcript
- Lucas: Let’s talk about the thing that made the modern city possible but also arguably made our workdays longer. I’m talking about the elevator. Specifically, the safety elevator invented by Elisha Otis in eighteen fifty-four. Luna: Right, because before that, you really didn’t want to go above the second floor if you were carrying anything heavy or valuable. Lucas: Exactly. And once you have reliable vertical transport, you can stack offices. You get density. But here is the puzzle: we have had elevators for a hundred and seventy years now. Yet, if you look at output per worker in typical knowledge jobs, it hasn’t necessarily scaled with building height. In fact, some data suggests face to face interaction time dropped as buildings got taller. Luna: That’s an interesting counter-intuitive point. Does height actually create isolation? Lucas: It does, if you think about the friction of movement. In a one-story campus, like the old Bell Labs complex, people bumped into each other. Innovation happened in the hallway. In a forty-story tower, you are locked in your pod until you deliberately schedule a meeting. The casual collisions vanish. Luna: So the very tool that saved land space might have cost us spontaneous collaboration. Lucas: Precisely. And this matters right now in September of twenty twenty-six, as companies are debating return to office mandates. They are trying to recapture that magic, but they are doing it in buildings designed for efficiency, not connection. Luna: But wait, surely the economic benefits of density outweigh the loss of hallway chats. Land is expensive. Lucas: Land is incredibly expensive. That is the primary driver. By stacking workers, you reduce the commute distance for many. You concentrate infrastructure. The aggregate productivity gain from being in a major hub is massive compared to suburban sprawl. Luna: So we trade horizontal spread for vertical concentration. It seems like a net positive for the economy overall. Lucas: For the macro economy, yes. But for individual firm performance, it depends on the type of work. If you are processing transactions, height doesn’t matter much. If you are designing new products, the lack of serendipity can be costly. Luna: I remember reading about how some tech firms built fake campuses to mimic those old Bell Labs environments. Lucas: Yes, and it highlights a key insight: architecture shapes behavior. When you build vertically, you must intentionally design for interaction. Otherwise, you just get efficient silos. Luna: Did the elevator change how we view time itself? Waiting for an elevator feels different than walking down a hall. Lucas: That is a great point. The waiting time adds a psychological barrier. You don’t just pop into someone’s office. You have to coordinate. This formalizes communication. It moves us from informal chat to scheduled meetings, which are more productive but less creative. Luna: So we optimized for predictability over possibility. Lucas: Spot on. And this trade-off is becoming even sharper with remote work. If everyone is distributed, the elevator becomes irrelevant. But then we lose the density benefits entirely. Luna: Which brings us back to the hybrid model. Companies are trying to find a middle ground where physical presence is meaningful. Lucas: They are. And some are redesigning offices to force those horizontal interactions back. More common areas, fewer private offices. It’s a reaction against the sterile tower model. Luna: It sounds like we are learning that tall buildings aren't automatically better for creativity. Lucas: Not automatically. They require deliberate management of social space. The elevator gave us height, but we still have to figure out how to keep people connected across those floors. Luna: Do you think future buildings will look different to address this? Lucas: I suspect we will see more 'vertical neighborhoods.' Smaller clusters of teams on shared floors, rather than one giant department per level. It reduces the travel distance between collaborators. Luna: That makes sense. It’s like bringing the campus feel up into the sky. Lucas: Exactly. And it acknowledges that while the elevator solved the problem of access, it created a new problem of cohesion. Luna: Interesting. So the next big innovation in office design might not be tech, but spatial organization. Lucas: I think so. Technology handles the execution. Architecture handles the inspiration. We need both. Luna: Before we wrap up, I want to mention something important about how we produce these conversations. Lucas: Right. We deliberately choose not to run ads on these shows. It keeps the content focused on what matters to you, without interruptions or sponsor bias. Luna: If you find value in this deep dive into economic history and workplace trends, please consider supporting us directly. You can visit buy me a coffee dot com slash fexingo to help keep the show ad-free. Lucas: Your support allows us to continue exploring these nuanced topics in depth. Thank you for listening. Luna: So, back to the idea of vertical neighborhoods. Do you think this will become the standard for high-rise offices in the next decade? Lucas: It likely will. As companies realize that mere proximity isn't enough, they will invest in designs that foster genuine interaction. The elevator gets you there, but the layout keeps you engaged. Luna: It’s a fascinating reminder that tools shape us as much as we shape them. Lucas: Absolutely. We built the elevator to save space, but now we have to rebuild our spaces to save our connections.
